Poll on Coulter.

Come on, folks.

You've got about 20 minutes to solve that one if you want to be decently placed.

It took me about 2.5 but I've got the benefit of a math degree on you folks...

Why would I tell you? So that you can go look it up?

4.

EDIT: nope

Stupid girl!

No, just because I'm wondering what level it's at.


You do have roughly 8 years on sky and 8.5 on me, IIRC.

BTW, what sort of degree and what college?


I'm having so much fun threadjacking.

It's not that difficult a question. In fact, it's the easiest question from the exam I'm looking at...

Hint: the prime factorisation of 2004^100 is:

2^200 * 3^100 * 167^100

It's all combinatorics from then on....

I'm aware of that. I was going to let kuciwalker go for it, because he is better than me at math I (or at least better educated.)

I have never solved a problem like this one, so I'd have to figure out a method on my own.
